Jenkins与Git持续集成&&Linux上远程部署Java项目
一、环境搭建1、安装所需软件
[*]Jdk
[*]Maven
[*]Jenkins
[*]Tomcat
[*]Xshell
[*]git
以上软件去官网下载，比较简单，不一一描述了
2、安装所需的jenkins插件
[*]Git plugin
[*]GitHub plugin git插件，download代码至本地
[*]Mailer Plugin 邮件插件
[*]Publish Over SSH 远程访问Linux服务器插件
打开jenkins—》系统管理—》管理插件—》可选插件，输入要下载的插件，勾选直接安装，安装完成页面勾选重启，插件安装成功

3、配置jdk\maven\tomcat环境变量
路径：我的电脑---》属性—》高级系统设置—》环境变量
[*]Jdk环境变量配置
JAVA_HOME: C:\Program Files\Java\jdk1.8.0
CLASSPATH: .; %JAVA_HOME%\lib\dt.jar; %JAVA_HOME%\lib\tools.jar
PATH: %JAVA_HOME%\bin; %JAVA_HOME%\jre\bin
[*]Maven环境变量配置
M2_HOME: C:\maven
MAVEN_OPTS: -Xms256m -Xmx512m
PATH: %M2_HOME%\bin
[*]Tomcat环境变量配置
CATALINA_BASE：c:\tomcat
CATALINA_HOME: c:\tomcat
CLASSPATH : %CATALINA_HOME%\common\lib\servlet.jar
PATH: %CATALINA_HOME%\bin; %CATALINA_HOME%\lib
[*] Linux环境变量配置
修改etc/profile文件，文件末尾添加
# jdk1.8 settings
JAVA_HOME=/usr/java/jdk1.8.0_51
JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH>#tomcat settings
CATALINA_HOME=/usr/local/tomcat
CATALINA_BASE=/usr/local/tomcat
export CATALINA_HOME CATALINA_BASE
保存，执行source /etc/profile生效
然后在tomcat/bin/目录下创建setenv.sh文件，文件内容如下
#!/bin/bash
CATALINA_HOME=/usr/local/tomcat
CATALINA_PID=$CATALINA_HOME/bin/CATALINA_PID
ID=`ps -ef | grep java | grep tomcat|awk '{print $2}'`
echo $ID
for> do
echo $id > $CATALINA_PID
done
JAVA_OPTS=`-Xms512m -Xmx1024m -Xss1024K -XX:PermSize=512m -XX:MaxPermSize=1024m`
JAVA_HOME=/usr/java/jdk1.8.0_51
JRE_HOME=/usr/java/jdk1.8.0_51/jre
在tomcat/bin目录下创建CATALINA_PID文件
把setenv.sh文件内容copy至/bin/catalina.sh文件
Linux环境变量配置是为解决后面执行shell脚本时重启tomcat报错
4、修改maven配置文件，修改版本库地址和jdk版本
修改配置文件：maven—>conf-->settings.xml
jdk默认是被注释的，放开后，修改为当前安装的jdk版本，否则构建时会报错
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217103649769-736415169.png
创建maven版本库地址，然后在settings.xml中添加版本库地址
添加<localRepository>D:/repository</localRepository>一行代码，如图
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217103721207-928883637.png
5、配置远程tomcat站点，创建站点文件夹（存放war包）
修改tomcat下server.xml文件
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217103759535-1794432241.png
二、构建java项目
1、设置jenkins全局变量
打开jenkins，进入系统管理，
lMaven\JDK\git安装目录，如图
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217103827800-98301133.png
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217103856472-249040454.png
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104041066-2017990380.png
l配置邮件通知，此处的邮件地址要跟管理员一样，勾选发送邮件测试配置，输入收件人地址，若配置成功，会收到测试邮件
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104151191-720862106.png
l选择要发布的具体位置，输入以下内容后，点击test configuration，验证是否连接成功
SSH Server Name: 远程连接名字，随便起
HostName:远程主机ip
Usename:远程登录名
Remote Directory:发布远程目录
Passphrase/Password: 远程登录密码
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104229066-977484526.png
2、创建maven项目，修改配置项
l新建job,选择构建一个maven项目
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104247800-2080207041.png
l配置job
[*]源码管理：输入git地址
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104309832-1993390072.png
[*]构建触发器：勾选Build whenever a SNAPSHOT dependency is built，建立快照依赖关系
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104321082-1463785955.png
[*]构建文件：构建pom文件（pom相对路径，Jenkins识别路径至workspace）+构建命令clean install -P test/-P pro
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104332769-581211953.png
[*]远程发布信息：
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104437019-2064165258.png
[*]设置发送邮件通知，构建不稳定时和构建失败时发送邮件通知
https://images2015.cnblogs.com/blog/802992/201702/802992-20170217104505754-103281228.png
三、编写脚本并发布
1、编写shell脚本，脚本上传至远程机器
https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gifhttps://images.cnblogs.com/OutliningIndicators/ExpandedBlockStart.gif
#!/bin/bash
export LANG
="en_US.UTF-8"
PROJECT
=admin
BACK_DIR
=/usr/local/autodeploy/back/$PROJECT
TEMP_DIR
=/usr/local/autodeploy/temp/$PROJECT
TOMCAT_HOME
=/usr/local/tomcat
WEBAPPS
=webapps_jfadmin
if [ -f $TEMP_DIR/$PROJECT.war ]; then
echo
"=======If temp exists war,finding tomcat PID======"
echo
"===================killing tomcat================="
ID
=`ps -ef | grep java | grep tomcat|awk '{print $2}'`
echo $ID
for>
do
kill
-9 $id
echo
"killed$id"
done
echo
"===================killed tomcat==================="
echo
"===================shutdown tomcat==================="
#shutdown tomcat
cd $TOMCAT_HOME
/bin
sh shutdown.sh
#sleep3
if [ -f $TOMCAT_HOME/$WEBAPPS/$PROJECT.war ]; then
echo
" If /usr/local/tomcat/webapps_jfadmin/admin.war exists,it will delete old war and its folder"
echo
"=================deleteing old war ================="
rm
-rf $TOMCAT_HOME/$WEBAPPS/$PROJECT.war
rm
-rf $TOMCAT_HOME/$WEBAPPS/$PROJECT
else
echo
" ===================old war not exits==================="
fi
echo
" Copying /usr/local/autodeploy/temp/admin.war to /usr/local/autodeploy/tomcat/webapps_jfadmin"
#echo
"===================copying new war==================="
cp $TEMP_DIR
/$PROJECT.war $TOMCAT_HOME/$WEBAPPS/$PROJECT.war
echo
" ===================backing war==================="
echo
" Creating the back folder "
mkdir
-p $BACK_DIR
echo
" Backing /usr/local/autodeploy/tomcat/webapps_jfadmin/admin.war to /usr/local/autodeploy/back/admin,and named by date"
cp $TOMCAT_HOME
/$WEBAPPS/$PROJECT.war $BACK_DIR/"$PROJECT"_`date +%Y%m%d%H%M%S`.war
#echo
"===================deleting temp file==================="
echo
" Deleting /usr/local/autodeploy/temp/admin/admin.war"
rm
-rf $TEMP_DIR/$PROJECT.war
#start tomcat
echo
"===================starting tomcat==================="
cd$TOMCAT_HOME
/bin
shstartup.sh
echo
" ===================finished!=========================="
else
echo "===================temp file not exits==================="
fi
shell脚本
2、发布
进入jobs列表，点击构建即可

构建成功，如下图所示
